By November 1921 the Thayer magic company in America was advertising a version for sale. The success of Selbit and then Goldin led to more and more magicians trying to imitate them with copies or improved versions of sawing illusions. Goldin later developed a sawing illusion that dispensed with boxes and used a large buzzsaw. This process was then reversed, and the assistant released unharmed. Goldin sawed through the middle of the box, inserting metal sheets to cover the cut ends, and then pushed the two halves a little way apart. Goldin's assistant lay in a box from which her feet, head and hands protruded. Later in 1921, Horace Goldin, a magician working in the United States, presented the first version which might look familiar to modern audiences. ДЄ later iteration of Horace Goldin's version of the trick, with a buzzsaw blade In the public performance the role of victim was taken by principal assistant Betty Barker. According to Jim Steinmeyer the woman who participated in the December 1920 demonstration was Jan Glenrose, who was Selbit's main assistant at that time and who was also the partner of magician Fred Culpitt. The question of who was the first woman to be sawn in half has received much less publicity than the question of which magician first presented the illusion.

It is generally accepted that the first public performance of a sawing illusion was achieved by British magician P. Wherever the idea originated, until the 1920s it remained just an idea for an effect, rather than a practical application of a method. It was suggested during a court case in 1922 that the trick can be traced back to ancient Egypt however, this claim has not been substantiated. Modern magic inventor and historian Jim Steinmeyer has concluded that there was probably no real Torrini and the story was merely a way for Robert-Houdin to play with ideas.

In his Memoirs, written in 1858, Robert-Houdin described a sawing illusion performed by a magician named Torrini. However, it is more likely that the story is a fiction which has its roots in the writings of the famous French magician Jean-EugГЁne Robert-Houdin. There remains a debate about the origin of sawing illusions, with some sources saying a magician named Torrini may have performed the first version in front of Pope Pius VII in 1809. 2.12 Criss Angel's pulling a woman apart.
